First arresting

Silicon was first found in 1823 by Jons Berzeius. He was a Swedish scientist living in Sweden. Jons Berzeius was born in 1779 and died in 1848 in Sweden. He was a famous chemist and worked hard throughout his life time and found many elements including selenium, cerium, thorium, silicon, and several other elements.

Report of first arrest

Silicon was first discovered in 1823 by Jons Berzeius. He found it by heating chips of potassium in a silica container and then carefully washing away the residual by-products.

Last seen

The silicon element is number 14 on the periodic table. Its atomic mass is 28.0855.

Known Associates

Though silicon(Si) is very stable, if it is mixed with oxygen(O2), silicon dioxide(SiO2) is formed. Silicon mixed with nitrogen(N2) makes 2SiN. Silicon mixed with 2N2 makes Si3N4.

Warning Label

Though silicon is a very stable element, if one breathes it in to much, in a powder form, one will develop respiratory problems, and may cause cancer.


Sand is an example of silicon mixed with other elements.
